"For our raw materials platform, Mark Millett has the unique strengths that will allow us to take full advantage of the opportunities in growing and integrating OmniSource with Steel Dynamics, as well as to continue to develop and implement our critical iron-making initiatives. Dick Teets has excellent management and technical skills to lead the growth of our steel operations, the company's primary business. Gary Heasley's industry experience permits him to focus on the strategic and operational opportunities in the fabricating side of our business and to continue to explore and execute M&A, joint-venture, greenfield, and other business opportunities.
